Answer:

19.5

Step-by-step explanation:

16,17,17,17,17,19,19,19,19,21,22,22,23,25

16+17+17+17+17+19+19+19+19+21+22+22+23+25=273

273 divided by 14 = 19.5

Answer:

19.5

Step-by-step explanation:

To find mean, you have to add all of the numbers in the data set together. After that, take the number of numbers in the data set, and divide that by the all of the numbers added up.

So for this situation, it's on a graph, so you have to make a note of the dots on the points. The data set should look like this:

16, 17, 17, 17, 17, 19, 19, 19, 19, 21, 22, 22, 23, 25 .

When added together, the total is 273.

From there, divide 248 by the 14 numbers in the data set, and you'll get 19.5, which is the mean.

A math class is having a discussion on how to determine if the expressions 4 x minus x + 5 and 8 minus 3 x minus 3 are equivalen

Brut [27]

Answer:

Both expressions should be evaluated with two different values. If for each substituted value, the final values of the expressions are the same, then the two expressions must be equivalent.

Step-by-step explanation:

<u>Given expressions</u>

4x - x + 5 = 3x + 5
8 - 3x - 3 = -3x + 5

Compared, we see the expressions are different as 3x and -3x have different coefficient

<u>Answer options</u>

Both expressions should be evaluated with one value. If the final values of the expressions are both positive, then the two expressions must be equivalent.

Incorrect. Positive outcome doesn't mean equivalent

----------------------------------------

Both expressions should be evaluated with one value. If the final values of the expressions are the same, then the two expressions must be equivalent.

Incorrect. There are 2 values- variable and constant

----------------------------------------
